Krill Oil 500mg +

Krill oil is derived from krill, which are small, shrimp-like crustaceans found in the oceans. They are a crucial part of the marine food chain, consumed by larger marine animals such as whales, seals, and penguins. So it is vital that they are sourced sustainably.

Krill oil supplements have gained popularity as an alternative to fish oil supplements due to a number of advantageous properties and their potential benefits.

One of the notable characteristics of Superba® Krill Oil is that its omega-3 fatty acids are mainly bound to phospholipids. Phospholipids are a type of fat that forms the structural components of cell membranes in the human body. This unique composition is believed to enhance the absorption and utilization of Omega-3 fatty acids in the body compared to other marine sources.

Additionally, krill oil does not exhibit a fishy aftertaste or smell after consumption.
Krill oil helps support heart health, brain health, and eye health.

Great company

I have been a
customer of Pureclinica for a number of years and their products without very best quality and several months ago when they had sold out and I "chased" them up wanting to know when they were getting more supplies.
Other items which I buy from Pureclinica are of equal quality but the Krill Oil is at the top of my list. Many tphanks Pureclinica

good for your heart

I figure if I take what's recommended by John Hopkins, the Mayo Clinic, and my own doctor to give the best chance of living a long and fit life, then I should be ok. And honestly, they work. I used to have all the symptoms of bad cardiovaslcular health from years of smoking, including numbness in my hands, shortness of breath doing simple things like going up stairs, sharp pains in my chest, bruise easily..... Since making some big changes to my diet and exercise,I was getting a lot better. I lost over 60lbs and my blood tests came back much better. At some point I became a bit obsessed with getting healthy and I got I into biohacking. That's when I found out about the benefits of krill oil and started taking it at the recommended dose. When I found out about Superba Krill, I knew I had to switch and I found Pureclinica on google. They offer a really great price for this brand of krill, and in the perfect dose for me. They come well packaged and they don't have any fishy smell. They're also registered with Aker (the manufacturer and owner of the superba brand krill) so you know it's the real stuff. I definitely recommend anyone looking to improve their cardiovascular health look into krill.

The best source of Omega-3s

After years of trying different Omega-3 supplements, Ive settled on krill oilspecifically Superba krill oilas my go-to, and for good reason. First off, Ive become really cautious about the quality of Omega-3 supplements, especially after learning about the sketchy stuff involved in farming fish for oil. Farmed fish are often exposed to a cocktail of chemicalspesticides, antibiotics, even PCBsand thats before you even get to the fact that theyre fed an unnatural diet of corn, soy, and other fillers that fish in the wild wouldnt touch. This all results in lower levels of DHA and EPA, which are the main reasons were taking Omega-3 supplements in the first place.

Thats where krill oil comes in, and Superba krill oil, in particular, has really impressed me. For one, krill arent exposed to the same chemical pollution as farmed fish, because theyre harvested from clean waters far from industrial contamination. The purity alone makes a huge difference. Plus, the Omega-3s in krill oil are in a phospholipid form, which means theyre easier for your body to absorbno need for extra processing. Ive noticed that with fish oil, my body seems to work harder to get the same benefits. With krill oil, it feels like my system puts the nutrients to use more efficiently.

Superba krill oil is also packed with astaxanthin, which Ill admit I didnt know much about until I dug into some research. Turns out, its a pretty powerful antioxidant that helps with long-term vision protectionsomething I wasnt even thinking about when I first started taking Omega-3s.

And then theres the practical stuff. Ive had my fair share of those dreaded "fish burps" with other supplements, but thats never been a problem with Superba krill oil. The capsules are small, easy to swallow, and dont have that gross fishy aftertaste. Ive been taking two a day, six days a week, for almost eight months now, and honestly, I feel great my skin looks and feels amazing, and my husband the same. Id recommend it to anyone looking for a reliable Omega-3 source, especially if youre looking to avoid all the potential downsides of fish oil.

In short, if you're serious about your Omega-3 intake and care about quality, Superba krill oil is far superior to all others. It's a step up from the typical fish oil products out there, and it's one I trust.

Frequently Asked Questions

What Makes Krill Oil Unique?

Krill oil, particularly Superba Krill Oil, is unique due to its natural combination and high concentration of four key nutrients: Omega-3 fatty acids (EPA & DHA), phospholipids, choline, and astaxanthin. This unique blend offers a wide range of health benefits supported by a growing body of evidence.

1. Omega-3 Fatty Acids (EPA & DHA):
These essential fatty acids are among the most researched nutrients, providing numerous health benefits for the heart, eyes, liver, and brain.

2. Phospholipids:
Phospholipids help integrate omega-3s into cell membranes more effectively, potentially offering better delivery to the body’s organs compared to other marine oils.

3. Choline:
Choline is vital for nerve signaling, liver function, and muscle functioning. Since our bodies can't produce enough choline on their own, it is essential to obtain it from our diet.

4. Astaxanthin:
This natural antioxidant not only gives krill oil its distinctive red color but also protects it from oxidation, eliminating the need for added preservatives.

Together, these components make Superba Krill Oil a superior choice for promoting overall health and wellness.

How do you know the Krill oil fishing is sustainable?

Our Ultra Pure Krill Oil, sourced directly Aker BioMarine stands out for its sustainability due to the advanced fishing methods and rigorous environmental practices employed.

Aker BioMarine utilizes proprietary Eco-Harvesting technology, which involves keeping a small trawl submerged continuously at an exact depth. This method ensures that the krill are gently brought on board via a hose, significantly reducing the risk of by-catch of other species. This environmentally friendly approach forms the cornerstone of their operations.

The krill fishing vessel operates in the pristine waters of the Antarctic, specifically in Area 48, just below the tip of South America. Recognized globally for its sustainable practices, Aker BioMarine is committed to responsible operations, under the principle, "Either we do it in a sustainable way, or we don't do it at all," underscoring their dedication to preserving the Antarctic ecosystem from the very beginning of their operations.

The sustainability of Aker BioMarine's practices is independently recognized. The fishery has been rated as the world's most sustainable reduction fishery by the Sustainable Fisheries Partnership (SFP), receiving an 'A' rating for five consecutive years. This rating reflects the excellent condition of the fish stocks and the well-managed practices in the Atlantic Southern Ocean.

Aker BioMarine was also the first krill fishery to receive the Marine Stewardship Council (MSC) certification in 2010, with re-certifications following in subsequent years, most recently in 2020. This certification ensures that their harvesting methods are sustainable and that all products are traceable throughout the supply chain.

Before beginning their operations, Aker BioMarine engaged in dialogue with WWF-Norway to ensure minimal environmental impact, highlighting their proactive approach to sustainable practices.

By sourcing Superba Krill directly from Aker BioMarine, we ensure that our Ultra Pure Krill Oil is both effective for health and environmentally responsible. This partnership allows us to provide you with a product that supports your wellness while also preserving the delicate marine ecosystem of the Antarctic.

Which is Better: Krill Oil Capsules or Omega-3?

When comparing krill oil capsules to traditional omega-3 supplements, krill oil has emerged as a unique and sustainable source of omega-3 fatty acids, offering numerous health benefits and are often considered the better choice for those seeking an effective and eco-friendly omega-3 supplement.

Seven key advantages of krill oil over standard Omega-3 capsules:

1. Abundant Species with a Stable Biomass:
Krill are one of the most abundant species on the planet, and their biomass remains stable. This abundance ensures a consistent and reliable source of krill oil without the risk of overfishing.

2. Sustainable and Precautionary Fishery:
Krill oil is sourced from fisheries that prioritize sustainability. Aker BioMarine - our supplier, for instance, operates under strict guidelines to ensure minimal environmental impact and has received high ratings for its sustainable practices.

3. Omega-3s in a Unique Multi-Nutrient Composition:
Krill oil contains omega-3 fatty acids in a unique multi-nutrient composition, including phospholipids and choline, which are not typically found in traditional omega-3 supplements. This combination enhances the overall health benefits.

4. Easy Absorption and Digestion:
The omega-3 fatty acids in krill oil are in the exact form our cells need, which allows for easier absorption and incorporation into cell membranes. This means that the body can more efficiently utilize the essential nutrients provided by krill oil.

5. Unmatched Purity, Freshness, and Quality:
Krill oil is known for its purity and freshness. It contains astaxanthin, a natural antioxidant that helps preserve the oil, maintaining its quality without the need for added preservatives.

6. Multiple Health Benefits:
Krill oil offers numerous health benefits due to containing the fatty acids DHA and EPA, while also benefiting from the presence of antioxidants.

7. Resilient Supply Chain:
The supply chain for krill oil is resilient and stable, ensuring a consistent supply at stable prices. This reliability makes krill oil a secure choice for those looking to incorporate omega-3s into their daily regimen.

While traditional omega-3 supplements provide essential fatty acids, krill oil capsules offer a superior alternative due to their unique composition, better absorption, sustainability, and additional health benefits.

What is the expiry date?

The shelf life stands at 2 years from date of manufacture and we receive freshly produced batches of our Ultra Pure Superba Krill Oil every 3 or 4 months.
